description Heat waves and urban heat islands are phenomena that affect human life. The purpose of this study is to investigation the relationship between heat waves and urban heat islands in the Ahvaz metropolis from 2003 to 2018. For this purpose days with a temperature higher than +2 standard deviation ) and lasted at least 2 days, were identified as days with heat wave using the Fumiaki index, to investigate the effect of heat waves on the intensification of heat islands , heat islands for daytime and nighttime days with the heat wave and a normal day with the lowest maximum temperature as a day without heat wave, the occurrence of each heat wave was calculated using MODIS-AQUA data. According to the results, most of the heat waves in Ahvaz which occurred in March 2010, were at the end of the cold period. In terms of continuity, it was 7 days and long-term. findings also showed that in heat wave and no heat wave conditions, often formed on the day the cold island and at night the heat island, but in the heat wave conditions during the day the cold island it has been often more severe than normal days, and at night time the heat island is often more intense than normal day. In general, the occurrence of heat waves has an effect on the intensification of the thermal islands of Ahvaz in both hot and cold months. these conditions have been more noticeable in warm months than cold months.
